Specification forming part of Letters Patent No. 36,l98, dated August 12, 1862.

To all whom it may concern.-

Be it known that I, ENOCH G. TOBEY, of Portland, in the county of Cumberland and State of Maine, have invented a new and useful Improvement in Lanterns for Kerosene- Oil; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of my improved attachment for kerosene-oil lanterns. Fig. 2 is a vertical section of a lantern and kerosene-burner with my attachment applied to it.

The same letters of reference in both figures indicate corresponding parts.

Several changes have been made in lanterns and their burners for the purpose of adapting them to the burning of coal or kerosene oil without a chimney; but these changes havenot effectually accomplished the end desired viz., the perfect combustionlof the oil and the prevention of smoke above the tip of the flame.

My improvement is designed to obviate the I smoking of kerosene-oil lanterns by producing a more perfect combustion of the volatile substance atand about the base of the flame. To this end I employ an ordinary lantern, A, and an ordinary kerosene burner or lamp, B, and use the same in the ordinary manner; but to the inner flange, a, of the base-trimming b of the lantern I attach, by means of springs c c, a cap, 0, said cap being of semispherical, conical, or other similar form to that represented, and extending up into the globe of the lantern a sufficient distance to allow the burner of the lamp, excepting the slotted apex of the cone d, to stand under it, as represented. Through the center of this cap an orifice, e, is out, said orifice being made flaring andof a size corresponding to the cone d of the burner or lamp B, so that when the lamp is attached to the lantern the cone d shall extend up through it and be snugly hugged all round, as shown. There would not be much objection to a narrow space existing between the cone d and the boundary at ff, to pass through the perforations of the base-support g of the cone d, and also through the perforations of the cone itself, and thus 4 pass directly to the base or blue portion of the flame, and at that point promote perfect combustion. This arrangement excludes the current from the top and sides of the flame, and 7 therefore blowing out and flaring of the flame are not experienced.

To detach the cap 0 for the purpose of cleaning the globe, &c'., the lamp is first withdrawn by pressing the springs h it toward one another, and then by pressing the springs c c apart the cap is released and can be taken out or allowed to fall out. The cap might be fastened by springs set in its circumference, so as to bind against the flange a, or it might be fastened by the ordinary bayonet-fasteuing; or it might, in cases where the globe is made detachable from the trimming b, be permanently fastened to the lantern; or it might be so shaped as to stand over the base-support of the cone and attach to the top of the lamp B, and bind all around against the flange a. In this case large perforations would have to be made in the cap between the flange a and the top of the lamp.

The cap might be so shaped as to beused in connection with an ordinary Argand burner, as the combustion is so perfect with its use that a globe without a chimney or even a top Witness my hand and seal in the matter of I my application for a patent for improvement in kerosene-lanterns, this 6th day of May, A.
